Fix DWARF disassembly of DW_OP_const_type
While debugging another issue, I noticed that disassembling a DWARF
expression using DW_OP_const_type did not work.
disassemble_dwarf_expression was not properly decoding this operation.
This patch fixes the problem. Tested by re-debugging gdb.
I didn't write a test case because that seemed like overkill for
what's essentially a maintainer's helper.
The expression evaluator does decode this properly, so no other change
was needed.
